Following is the setup needed to run DoorMan with Wildcat IM: The only thing you need to do differently for IM is in the Bat/Run file that calls DoorMan. It should read as follows: CD DF LOCK %WCPORTID% DOORMAN %WCNODEID% DF OFF %WCPORTID% CD C:\WC30 DoorMan has been tested using that batch file on an 8-node Wildcat IM system and found to work flawlessly! I'm not exactely sure what he had his IRQs set to for each node, or if it even matters? I'd suggest trying setting them all to the same IRQ as your Digiboard first. Let me know if you have any trouble! Jerry Aldrich
